CARBURETER.

Patented Oct. 8, 1907.

Applica'lion filed April 7, 1905. serial No- 254,810.

To all whom it may concern:

.Be it known that we, Emroxo M. .I. WEINAT, a. subject of the Grand Duke of Luxemburg. now residing at Chicago, in the State of Illinois, and .Iosm'u Boom,

:1 citizen of the Republic of France, now residing at Chicago, Illinois, have invented certain new and useful Improvements in Carburetors, of which the following i a specification.

I Our invention relates to carburetors: or means for mixing the vapors of volatile oils with air to form an explosive mixture for gas engines and the like. Its primary objects ale, to provide automatic means for supplying the air and oil to the mixing chamber and intimately mixing them; to provide a superior spraying device for distributing the vapor of the oil, to provide a superior valve for controlling the outlet of the niixture and a superior means of flooding the carburetor at the beginning of its action, and to generally improve the construction and operation of carburcters.

These objects, and other advantages which will hereinafter appear, we attain by means of the construction illustrated in preferred forms in the accompanying drawing, wherein- Figure l is a. side elevation of the device;

Figure 2 is a plan view of the same;

F igure 3 is a top plan view of the air valve and section of the carburetor casing takenalong line (3) in Figure 4;

Figure 4 is a central vertical section of the carburetor taken on line (4) in Figure 2;

Figure 5 is a side elevation of the plunger of the vaporizing chamber, and Figure 6 is a central section of the other part of said chamber;

F igure 7 is a partial sect-ion oi the carburetor taken on line (7) in Figure 4 and showing the outlet valve closed;

Figure 8 is a partial central section showing a modification of the vaporizing chamber having a haflle plate device for facilitating the atomizing of the vapor,

- 13 for the mixture. It is closed at the top by a cap 14 through which extends the revolving stem 15 oi the air valve 16. This valve is engaged 'on its stem to rotate it, by the head 11 of the lever 18 which is operated by a. link 19, or any other handle as may hedesired.

$0 The head l7-and a rotating collar 17 are clamped together firmly by means of the two nuts 20 engaging the stem 15 and therefore the handle I8 is frictionally held on said stem. Communication between the lower side of the valve 16 and the upper part of the mixing 3 chamber is secured by means of the perforations 31 (see Figures 3 & 4) in such valve. The relative position of the handle 18 may thus be adjusted, and its rotation is governed by means of the collar 17. which has a. pin 22 working in the inclined slo: 21 in the part 2, as shown in Figure 1, for the purpose to be hereafter described.

The gasolene or other oil enters through the pipe 23 and passes upward through the puppet valve 24 which is carried on adjustable stem 25 fixed in the top of a. hollow float 2G and guided for vertical movement by extension of its stem into thevalve stem 15. The oil enters through the valve 24, into the chamber formed by the cup 27 and the plunger 28 fitting loosely therein, and supports the float 26, whichthus automatically operates the inlet valve to maintain a constant level. The plunger 28 has a stem 32 extending into the air valve stem 15, and a. spring 34 keeps the plunger in place and at the same time'suppdrts the plunger rod 33 which is used to operate'the' inlet valve 24 by hand, by press-j ing it down, engaging the stem 25 of said valve. By this means the oil chamber may be flooded at the starting of the engine, to give a richer vapor. 4

On the outside of the oil chamber 27 is formed a. conical flange 30, and the air valve 16 has an'inwardly sloping face 16 cooperating with the flange 30 making a. variable opening between them, through which the air from inlets 12 and 12 is drawn. Immediately above this annular opening the air passage expands, and meets the spray of the oil which is drawn by suction from the chamber 27 through the multiplex smallpasagcs lie-.25

tween cup 27 and plunger 28, formed by the cross grooves 29 on the surface of the cup; (see Figures 5 and 61) The lower rim of the plunger 28 is serraterl as shown in Figure 5 in order to keep clear passages 'under the plumgcr where it rests on the annular lodge in the cup 27.

The air valve. 16 has an upwardly extended flange or wing 16 which, when the valve is both elevated and rotated, covers the outlet 13. From Figure 1 it will be seen that this action is effected by rotating the handle 18 which causes the pin 22 to slide in the inclined slot 21 and raise the valve 16. The slot has a horizontal portion at the upper end, and further motion of the pin therein, and revolving the valve,.causes the'rring 16 to obstruct the mixture outlet 13, thus cutting off the a supply to the engine. It will benoted that the upward 1'30 motion of the valve 16 constricts the air inlet slit be tween 16' and W,- and that it entirely closes before th pin 22 strikes the flat portion of the slot 21 and the wing 10" closes the outlet 13. The proportions of air and gas may thus be altered without interfering with the outlet for the explosive mixture. While the oil cup-and the sliding valve 16 have been shown as circular, it will be understotid that these may be of square or other form, the essential featiu'e being the opening and closing of the air inlet bv sliding of one 11 of these parts on the other and the oil spray inlet. living contiguous to the air inlet. Also the elosing in; in" for the mixture outlet. may oi course be operated by simple vertical m vemen ol the valve it? \allen s-i desired; It. is (.0. he noted that the relative positions of the oil and air inlets causes the oil to be drawn in by suction and requires no pressure in the oil tank or feed pipe 23.

7 vapor to follow a devious path upward and heeome Lott,

In Figures 8 to 10 we have shown a nnnliiieil form of the closing plunger of theoil ehamher providing additional means for breaking up and mixing the oil vapor with the air Around an up ".ml extension of the plunger 28 are placed a series of serrated rin 2H. spared liy rings 35, and having their respective solid ortions 34 alternated with one another, thus causing the air and thomughly mixed. The structure above (llfit'lillttl gives a. very easy and certain feed of the oil, and the annular air inlet and mixing ehamlier renders-the, air lei-d free, readily cl'mtrollalile, and certain of very uniform and intimate mixture with the vapor.
